Title: Injection burner
Inventor: KAWAKAMI ISAMU
IPC: F23D11/10
Filed: 1982-10-08
Abstract: PURPOSE:To enable a flame to reach a long distance and prevent carbon produced from impurities in oil fuel from being adhered to a combustion opening at the burner by a method wherein the structure of combustion cylinder is improved. CONSTITUTION:In a burner in which oil fuel is injected into a nozzle 1 together with air, ignited in a combustion cylinder 2 and combustioned therein, an inner cylinder 3 having porous wall therein which is tapered to cause its extremity end to be narrowed is arranged in the combustion cylinder 2. Compressed air is fed into a secondary air feeding pipe 7, an outside part of the inner cylinder 3 in the cmbustion cylinder 2 shows a higher pressure to cause the secondary air to be injected through the porous wall in the inner cylinder 3. When the nozzle 1 is ignited, a flame A is enclosed by the secondary air injected therearound, while the flame is gradually narrowed due to the tapered inner cylinder 3, resulting in making a long flame. Further, the injection of the secondary air enclosing the flame prevents the carbon from being adhered to the inner cylinder and so a life of the burner is extended.

Filed: 1986-07-29
Abstract: PURPOSE:To reduce a spring constant of an elastic coupling, by making an inner member slidable relative to an outer member, and receiving an axial external force by the outer member. CONSTITUTION:An elastic coupling is rotated with a propeller shaft and the other shaft, thus effecting power transmission between the propeller shaft and the other shaft. When vibration and impact are axially applied to the propeller shaft, an inner member 21 is adapted to slide relative to an outer member 20 in a direction substantially parallel to a center axis M, and accordingly, the inner member 21 is slid to be displaced along a lubricating member 4. Accordingly, as the inner member 21 is displaced, an axial spring constant of the elastic coupling may be reduced almost irrespective of torsion and twist.
